Applications of dual-gate GaAs m.e.s.f.e.t.s for fast pulse shape regeneration systems

The suitability of dual-gate GaAs m.e.s.f.e.t.s for pulse shape reconstruction in the Gbit/s range is presented. The properties of these f.e.t.s and the circuitry for reduction of pulse width and pulse slope are both described. The variation of the input/output pulse-width ratio and the time behaviour for fast pulses are shown.
